I have an 05 WR450. The guy I bought it from put a lot of nice goodies on it. Free mods, fmf pipe and header, scotts, JD, etc... Its a good looking and running bike. Check that... this thing is a fire breathing, balls to the walls, rippin', runnin' beast. It definitely gets my adrenaline going, which I like a lot. However, I would also like it if I could tame it just a bit. I still want to go fast, but I am not necesarrily a "fast" rider all the time. I am intermediate level and want to slow down to enjoy the view. Is there a way were I could ever so slightly, remove some of the agressiveness and still have the adrenaline rush on tap? Am I making sense? I want to be able to also use this bike to go trail riding with my kids. Its a bit much for that right now. Keep in mind that I do go out with the boys and like to open things up a bit as well. Also, the FMF pipe and titanium header are really loud. Can anyone recommend a quieter pipe?
